A big block has higher weight and density in the block, as well as larger valve bores, a longer stroke, and a generally larger exterior size. A big block can have the same displacement as a small block, but only the most extreme small blocks encroach on this territory.
The Dodge Grand Caravan has been one of the top selling minivans since it was introduced for the 1984 model year. The Grand Caravan is so popular that more than 11 million units have been sold globally, with several million units having been sold in North America alone. With so many new units sold, you would assume that the Dodge Grand Caravan would be on a list of great used minivans. You would be wrong.
The single engine option in the latest models is a 3.6L V6 that offers 283 hp and 260 lb-ft of torque. The powerplant is mated to a six-speed automatic. The duo offers 25 mpg on the highway. That is solid fuel economy, if you can stand all of the cabin noise.
On paper, the Toyota Sienna seems to offer everything. It is roomy and has plenty of cargo space. Unfortunately, what looks good on paper isn’t always good in real life.
It also takes more torque to get oversized wheels turning which saps overall output and drains the gas tank much faster than normal. Swapping to lower gears and increasing the number in your gear ratio may be enough to offset the difference. A notable exception here is diesels, which sometimes put out so much torque that the difference with larger wheels isn’t noticeable.
Ford’s Special Vehicles Team (SVT) went to work on the 5.8-liter small block V-8 and managed to squeeze 240 horsepower out of it. A lowered suspension, new shocks, anti-roll bars and 17-inch tires put that power to the road and made the Lighting a great handling truck in addition to being a speed demon. The Lightning cranked up to 60 mph in 7.2 seconds and blazed through the quarter mile in 15.6 seconds. The biggest complaint about the Lightning was that it gulped down gasoline.
With bigger tires and heavier rims on your list of Jeep mods, the stock gear ratio may not be enough to get you where you want to go. This is where changing the gear ratio comes in handy and reduces unreasonable stress on the engine. If the wheels are too tall for the stock gear ratio, there will be a noticeable power drop off from its stock build.
One good option the Dodge Grand Caravan has to offer is the Stow ‘n Go second-row seating system that allows you to quickly store the center row of seats for extra cargo space.
